Abstract: Manufacturing methods for the formation of positive electrodes and the balancing of Coulombic capacities of positive and negative electrodes for use in a heterogeneous electrochemical capacitor (HES) having a PbO2|H2SO4|C system. Exemplary methods make it possible to manufacture capacitors with both non-formed and pre-formed positive electrodes. Capacitors produced by the exemplary methods may be used, for example, as secondary power sources to level loads of power networks, power electric vehicles, cellular and mobile communications, emergency lighting systems, telecommunications, and solar and wind energy storage devices.

Abstract: The present invention relates to the field of the synthesis of porous carbon materials and their use in the manufacture of electrodes with a double electric layer (DEL) for electrochemical capacitors having an aqueous and organic electrolyte having high specific energy parameters. The synthesis technology makes it possible to manufacture porous carbon powders made of carbohydrate substances with a low content of ash and metals in the powders with high specific capacitances and low specific electrical resistances.

Abstract: The present invention relates to a double electric layer heterogeneous electrochemical supercapacitor (HES) and a method of manufacture. Single-cell or multi-cell versions of the HES can be produced. Output characteristics of the HES are optimized by carefully controlling particular parameters of the HES' design and construction.

Abstract: A current collector for use in a capacitor having an aqueous or non-aqueous electrolyte, such as an aqueous sulfuric acid electrolyte. The conductive basis of the current collector may be manufactured from a number of conductive metals but, preferably, is comprised of lead or a lead alloy. The portion of the conductive basis that will be in contact with the electrolyte is provided with a protective layer that is created by deposition of one or more layers of one or more protective coating materials thereto. Each protective coating material is comprised of at least a conductive carbon powder and a polymer binder that is resistant to the electrolyte. Preferably, but not essentially, the protective coating material(s) are applied to the conductive basis in the form of a paste, which is subsequently subjected to a solvent evaporation step and a thermal treatment step. The resulting protective layer is also substantially devoid of pores through which the electrolyte can permeate.

Abstract: The invention relates to elecrical engineering and can be used for producing electrochemical double-layer capacitors having high specific energy and power characteristics and which can store and give off energy at high speed. The essence of said invention lies in the fact that the active mass of a negative polarised electrode (2) is an organic electroconducting polymer or composite which is based on a carbon or polymer material. A separator (3) is provide with pores which enables additional oxygen molecules to penetrate. The negative polarized electrode (2) is made of a polyaniline composite and an activated carbon material or of an activated carbon material composite and polypyrrole. Aqueous solutions of non-organic acids or mixture or salts thereof or thixotropic mixtures of acids and salts or solid proton conductive compositions are used as electrolytes.
